StructureDefinition: - Detailed Descriptions

Definitions for the StructureDefinition-us-core-birthsex Profile.

Extension
Definition	A code classifying the person's sex assigned at birth as specified by the Office of the National Coordinator for Health IT (ONC).
Control	0..1 This element is affected by the following invariants: ele-1
Comments	The codes required are intended to present birth sex (i.e., the sex recorded on the patient’s birth certificate) and not gender identity or reassigned sex.
Invariants	Defined on this element ele-1: All FHIR elements must have a @value or children (: children().count() > id.count()) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
Extension.id
Definition	unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Control	0..1
Type	string
Extension.extension
Definition	May be used to represent additional information that is not part of the basic definition of the element. In order to make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Control	0..*
Type	Extension
Alternate Names	extensions, user content
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Extension.url
Definition	Source of the definition for the extension code - a logical name or a URL.
Control	1..1
Type	uri
Comments	The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Fixed Value	http://hl7.org/fhir/us/core/StructureDefinition/us-core-birthsex
Extension.valueCode
Definition	Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list).
Control	0..1
Binding	Code for sex assigned at birth The codes SHALL be taken from US Core Birth Sex Value Set
